Windows Data Collector: WMI Connectivity
WMI is only used for connecting to a remote Windows Primary Server from a Centralized Data Collector or another subsystem that requires WMI. WMI uses DCOM for networking. DCOM dynamically allocates port numbers for clients. DCOM's service runs on port 135 (a static port) and any client communicating with a host connects on this port. The DCOM service allocates the specific port for the WMI service.

Customers must work with their Windows Hosting Team and Domain Admins for setting up WMI for their specific version of Windows and in alignment with their domain policies.
